Editing RealAudio (section)

==File extensions==
RealAudio files were originally identified by a filename extension of '''.ra''' (for Real Audio). In 1997, RealNetworks also began offering a video format called RealVideo. The combination of the audio and video formats was called RealMedia and used the file extension '''.rm'''. However, the latest version of RealProducer, Real's flagship encoder, reverted to using '''.ra''' for audio-only files, and began using '''.rv''' for video files (with or without audio), and '''.rmvb''' for VBR video files. The '''.ram''' (Real Audio Metadata) and '''.smil''' (Synchronized Multimedia Integration Language) file formats are sometimes encountered as links from web pages (see .Streaming Audio section below).
